摘要

Prolific sows have high annualized culling rates, which is both an economic and animal welfare issue. In many commercial operations, sow output falls considerably short of their potential. In Europe, the average sow lifetime is lower than 5 parities,and the average sow replacement rate is higher than 45%. Replacement gilts and first and second parity sows together can account for around 45% of total culls (Lucia et al., 2000) resulting in herd inventories dominated by a high percentage of young females.
